I have friend that has a single internet connection in his store and wants to offer guest wifi but he does not want to pay for a second connection! He has a point of sale system with credit card processing running on this network and does not want to compromise the data, any suggestions how to do this with a single connection?

Most new Wi-Fi routers have this feature built into them. Even better is that he can control it with or without a password. He can even assign a different IP range or VLAN and put a time limit on it.  You would have to check to see what type of Wi-Fi device he is using.

Also, on a side note some cable providers like Xfinity will place a FREE hot spot in a place of business like a pizza place or coffee shop IF the business is using their business cable service.  This allows the business to have more clients enter to use the hot spot and as a result brings more business.

Check to see what type of router he is using for Wi-Fi.

He has Verizon Fios and I know it does not have this, and unless you get Verion FIOS 150mbit service you have to use their actiontec router. Any solution for this?

Yes he can. Assuming it's the typical ActionTech four port model he can purchase another wireless router and plug it into one of the open existing ports.  cable should be between the ActionTech switch ports and the switch ports of the new wireless. It will obtain a DHCP address from the ActionTech. At which time you can log into it and set up the guest Wi-Fi with the different ranges as I mentioned above.

well if he took this route what is the feature that I am looking for on the router?


second question from a security standpoint using this new router that you are talking about if someone knows something about networking:

Lets say his POS system is assigned a 192.168.1.0/24 range
and his guest wireless is assigned 192.168.2.0/24 range. Instead of connecting using DHCP they assign a static and guess  his POS IP range does the router prevent crossing into each others network?

by default typical TCP/IP fundamentals would not allow this if configured properly. That is why I mentioned that what you can do is give the guest wireless in another range that limits the amount of users and the subnet they are on. So using a 192.168.2.200 with a subnet mask of 255.255.255.240 will limit guest wireless to a pool of 15 connections and keep them on a separate network/ Make sure you assign them to VLAN 2 since the POS is on VLAN 1.

OK great, I forgot in the past I used a VLAN router by linksys for a totally separate situation, yes that should be a decent enough solution. Thank you.
